New bugs:

In the main menu and F3 monitor, the version number says 1.2, without noting it's a preview version.
If you attack a villager near an iron golem, the iron golem will remain passive.
Ocelots spawn outside of jungle biomes, at least in worlds generated in older versions. (noticed in taiga biome)
Monsters will be set to fire on direct sun only after they had been hit by the Player.
Mobs spawn inside trasparent blocks, like leaves

I was in my friend's branch mine and I noticed he left all the coal. I asked if I could mine it and he was like "Sure, I don't care about it". So I was mining away, and wouldn't you know I found a fucking vein of 8 diamonds hidden behind the coal. Lucky me :V

Possibly they're planning some kind of sand dungeon, and not telling us about it so it keeps a suprise

A dungeon or cave for every different biome is what I think they should add.
I know there was a mod for this but still, it'd be less trouble if it were official (since Redpower, I have no faith in installing a server mod ever again)

All that Minecraft is needing at the moment is more things to build with, such as furniture and other specialized decorations. Building has always been the strongest part of Minecraft so why not to build on that?

I always mine coal, you never know what goodies are hiding behind it. Besides, coal is useful in Redpower.

Y'know, I hope that the new Sandstone blocks allude to a sort of Sand Dungeon like a deep Pyramid or Sphinx, which like the Stronghold involves opening a portal to a new Boss, like the Dark Pharaoh Lehparsi, a nod to one of the more popular MC Machinimas out there.

I for one would love to see more adventure style dungeons.

I never played Aether mod, but the yogscast videos on it had those bronze, silver and gold dungeon things and they looked like a really cool idea.

Ugh. No HD packs, no optifine, no unbelievable shaders. I think I'll wait this one out. Also, does anyone happen to know if there is any 256x256 or one step lower like photo mod or whatever it's called?
